Study confirms Havieron pathway to a world-class, long-life, lowest
quartile cost Australian gold-copper mine, leveraging existing Telfer infrastructure
Steady state operations to generate pre-tax free cash flow of $739m p.a.1 ($1,197m p.a. at
spot gold2) from annual production target3 of 266koz Au & 9.6kt Cu, at $1,610/oz Au AISC4
Updated Ore Reserve of 38.5Mt at 2.63g/t Au & 0.33% Cu for 3.3Moz Au & 128kt Cu, the
largest Australian underground gold reserve outside of a global major gold producer
$1,065m pre-production capex expected to be fully funded from existing $750m cash,
ongoing Telfer cash flows and $500m debt commitment from Tier 1 lending syndicate5,6
Base case $2.9b post-tax NPV5% and 22.5% IRR ($5.4b NPV5% and 31.5% IRR at spot gold)
Conservative base case assumes standalone Havieron processing; potential for material
operating cost savings if Telfer mine life is extended and co-processed9
